RonaBond HB40 and HB40 Ultra Rapid Mortars for high build concrete repair on vertical and overhead surfaces Instructions for Use (continued) All removal of concrete and steel must be carried out in accordance with the specifiers recommendations. When repairing chloride contaminated concrete the method used to prepare and prime surfaces may differ and the Ronacrete Technical Department should be consulted. All surfaces must be cleaned to remove loose dust, debris and surface contamination which may prevent adhesion of the repair mortar to concrete and steel. Surfaces to be rendered must be cleaned...

RonaBond HB40 and HB40 Ultra Rapid Mortars for high build concrete repair on vertical and overhead surfaces Instructions for Use (continued) When applying multiple layers to achieve the total depth these can be built up monolithically (wet-on-wet) or after previous layers have firmed up. Keying and priming (with the appropriate primer) between hardened layers is necessary to ensure total adhesion through the repair or render. Finish the repair with a wood float, steel trowel or leave with a sponged finish as required. If applying a protective or decorative coating such a RonaBond Crack Bridging...
